How to trigger change detection in Angular2? [duplicate]

Answer 1

I'm not sure if it's better. There a couple of other ways I can think of.

Using NgZone

You can inject NgZone and execute the run method with a callback:

 NgZone.run(()=>this.currentUser.next(user));

Using setTimeout

setTimeout will trigger change detection automatically:

setTimeout(()=>this.currentUser.next(user));
